Latest Electrical phenomena Stories
A research team led by Professor Keon Jae Lee and Professor Yoon Sung Nam from the Department of Materials Science and Engineering at KAIST has developed the biotemplated design of flexible piezoelectric energy harvesting device, called "nanogenerator."
Until now, there has been a lack of quality in the materials used for most Electroluminescent parts, like EL Wire and EL Tape Inverters.
Unexpected behavior in ferroelectric materials explored by researchers at the Department of Energy’s Oak Ridge National Laboratory supports a new approach to information storage and processing.
NASA is preparing to launch an inexpensive, football-sized probe to study lightning, including its effects on the atmosphere and the possible link between the phenomenon and powerful energy bursts known as terrestrial gamma ray flashes.
Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light.
NASA’s FireStation instrument aboard the International Space Station (ISS) is helping scientists learn more about the party taking place inside a thunderstorm.
A detectable electrification of the air is caused by electrical currents born from thunderstorms. These currents flow through the atmosphere and around the globe, even in places with no thunderstorm activity.
A new experiment aboard the International Space Station (ISS) is looking into the strange things that come from the tops of thunderstorms. The experiment, called "Firestation" consists of a package of sensors designed to explore how the Earth mimics a supernova during thunderstorms.

When we think of thunderstorms we have to remember the deadliest part of those storms and that is the lightning that occurs with them. Lightning is found in many forms. The first type of lightning is known as cloud to cloud meaning that the electric charge travels from one cloud to the other. The second type of lightning is the Cloud to Air meaning the lighting moves from the cloud and enters the clear air of the sky. A third type of lightning is the cloud to ground. This is the most...
A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...
Heat Lightning is actually faint flashes of lightning reflecting outward from distant thunderstorms. These flashes usually do not produce thunder as the storm is sometimes too far away to be heard. The term heat lightning got its name because it often occurs on hot summer nights and does not produce audible thunder. One reason heat lightning can be seen so far away is due to the reflection of the light bouncing off water particles in moist, humid air and as light is scattered throughout the...
Aurora -- The Polar Aurora are natural displays of light in the sky that can be seen with the unaided eye only at night. An auroral display in the Northern Hemisphere is called the aurora borealis, or the northern lights; in the Southern Hemisphere it is called the aurora australis. Auroras are the most visible effect of the sun's activity on the earth's atmosphere. The beautiful and often eerie curtains of light in the night time sky have been observed by people for millennia. An aurora...
